COMBINATION OF THF REVERSIBLE STEAM-TURBINE WITH LOCOMOTIVES ANDVEHICLES.

SPECIFICATION forming part of Letters Patent- No. 768,010, dated August16, 1904.

Application filed October 30, 1903. Serial No. 172,180. (No model.) I iTo a whom it may" concern: 1

Be it known thatI, GUsTAvUs S. GRANLUND, a citizen of the United States,residing at West Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Combination of theReversible Steam or Elastic-Fluid Turbine with'Locomotives and Vehicles,of which the following is a specification.

My invention relates to improvements in locomotives and vehicles inwhich a reversible turbine furnishes the propelling power instead of thereciprocatlng engines now 1n use; and

the objects of my invention are, first, to provide acontinuouslyrotating turbine shaft geared to the driving-axle of thelocomotive, thereby lessening centrifugal effectsof the reciprocatingengine; secondly, to obtain a greater degree of expansion of steam orgas by means of the compound reversible turbine. I attain these objectsby the mechanism illustrated in the accompanying drawings, in which nFigure 1 is a vertical section of part of the combination; Fig. 2, avertical section taken on line 1 2, Fig, 1'; Fig. 3, a top view of theturbine with the upper half of the shell or cover removed; Fig. 4:, aside view of the turbine with a section taken'on line 9 10, Fig. 5; Fig.5, a top View of the turbine with a section taken on line 11 12, Fig. 8.Fig. 6 is a vertical section of turbine, taken on line 7 8, Fig. 5; Fig.7, a vertical section of turbine, taken on line 3 l, Fig. 5; Fig. 8, avertical section of turbine, taken on line 5 6, Fig. 5.

Similar letters refer to similar parts throughout the views.

The turbine-shaft P, to which are secured the vanes or fans I, Z, O, andU, is geared to the locomotive driving-axle N by the gears X and Y, Fig.3. The steam-pipe B, Fig. 1, communicating between the steam dome A ofthe steam-generator M and the turbine by the steam-passages r and s,carries the valve-seats z z, in which the piston-valves h and k arereciprocated by the rod Z, attached to the lever G.

being supported on the locomotive drivingaxle by the bearing Q, attachedto the shells T and R by the webs wand o.

The reversing-shaft L, supported by the bearings M and M, Fig. 5,carries the levers d, 7), and m, operating, respectively, thereversing-valves B, Fig. 6, B, Fig. 8, and B Fig. 7, the shaft L beingoscillated by the connecting-rod A, attached to the reversinglever F,and connected to the crank C on shaft L, Fig. 5.

The exhaust-pipe E carries the exhauststeam from the turbine to thesmoke-stack of the steam-generator M.

When the locomotive is moving forward, the valves are reciprocated, sothat valve K uncovers steam-passage S, causing the steam from dome A ofsteam-generator M to flow through passage D, Figs. 1 and 4, and impinge'on vanes or fans 1, Figs. 3 and L, causing the shaft P to rotate in aright-handed direction. The steam then escapes through passage B, Fig.4, and shaft L having been oscillated passage C, Fig. 6, will be openand the steam impinge on vanes Z, whereupon it passes through passage Cinto passage F", Fig. 8, impinging on vanes O, whence it passes throughpassage E and into passage D9, Fig. '7, impinging on vanes U, afterwhich it passes through exhaust-pipe E into the smoke-stack.

When the locomotive is moving backward, the valve h is reciprocateduntil it uncovers passage r, Fig. 1, allowing steam from dome A ofsteam-generator M to pass through passage C, Figs. 1 and t, and impingeon vanes I, after which it escapes through passage B and flows throughpassage C Fig. 6, impinging on vanes Z. Passing through passage C thesteam flows through passage F, Fig. 8, expanding on vanes O, whereuponit passes through passage E and into passage 1), expanding upon vanes U,Fig. 7 after which it exhausts into pipe E.

The front end of the turbine is supported by the bracket :21, Figs. 1,4:, and 5, resting on spring 2', Fig. 1, which is held by the plate 9upon the nut n of the bolt y, which is suspended from the angle-iron u,Figs. 1 and 2, resting upon the locomotive side frame f.

It is to be understood that the forms, dimensions, details, andmaterials employed in the construction of the combination may be variedwithout in any way changing the principle of the invention and that thewords locomotive and vehicle are intended to include traction-engines,railroad cars and coaches, and automobiles.

Although the steam-turbine has been shown and described, any elasticfluid other than steam may be used, such as compressed air, or anexplosive mixture of air and gas made from gasolene, kerosene, or coal.

As the steam or elastic-fluid turbine has been used in combination withtorpedo-boats, cruisers, yachts, and merchant vessels, I do not claimsuch combination broadly.

The turbine-shaft running faster than the driving-axle transmits powerthrough the reduction-gears.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

l. The combination with a locomotive or vehicle provided with a suitablerunning-gear including driving-axle and propelling Wheel or Wheels, of areversible steam or elasticfluid turbine comprising one or more seriesof vanes upon Which steam or elastic fluid 6X- pands,a reversingmechanism admitting steam or elastic fluid on either side of turbinedisks or vanes, a turbine-shaft connected with and arranged to runfaster than the propelling- Wheel or its axle, a suitablefuel-receptacle, a generator for steam or elastic fluid and avehicle-body adapted to the conveyance of pas sengers and goods, acontrolling mechanism for admitting or shutting off steam or elasticfluid, substantially as set forth.

2. The combination with a locomotive or vehicle provided with a suitablerunning-gear including driving-axle and propelling wheel or wheels, of areversible steam or elastic-fluid turbine comprising one or more seriesof vanes upon which steam or elastic fluid expands, a reversingmechanism admitting steam or elastic fluid on either side of turbinedisks or vanes, a turbine-slnrtt connected with and arranged to runfaster than the propellingwheel or its axle, a suitable fuel-receptacle,a generator for steam or elastic fluid, and a suitable connectionbetween the turbine and locomotive or vehicle running-gear, acontrolling mechanism for admitting or shutting ofl' steam or elasticfluid, substantially as set forth.

3. The combination with a locomotive or vehicle provided with a suitablerunning-gear including driving-axle or propelling wheel or wheels, of areversible steam or elastic-fluid turbine comprising one or morecompartments in which steam or elastic fluid expands, a reversingmechanism admitting steam or elastic fluid on either side of turbinedisks or vanes, a turbine-shaft connected with and arranged to runfaster than the propelling-wheel or its axle, a suitablefuel-receptacle, a generator for steam or elastic fluid, and suitabledevices fortransmitting motion from the tu rbine-sliaft to thedriving-axle or propelling-wheel, a controlling mechanism for admittingor shutting oif steam or elastic fluid, substantially as set forth.

The foregoing specification of my improved combination signed by me, inthe presence of two subscribing witnesses, on this 28th day of October,1903.
